Fig. 2 is the connection diagram of waste oil recovery pump of the present utility model and waste oil filter;
Fig. 3 is waste oil recovery process figure of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in detail.
As shown in Figure 1, the utility model comprises one for carrying the feed pipe 1 of sand washing water, and feed pipe 1 one end is connected (not shown) with offshore platform separator, and the other end is connected with the top inlet 21 of a horizontally disposed waste oil collecting tank 2.The inside of waste oil collecting tank 2 is divided into sand washing hydroecium 23 and a grease chamber 24 by the weir plate 22 vertically arranged.Be provided with a sewage draining exit 25 in the bottom of sand washing hydroecium 23, the water in sand washing hydroecium 23, sand, mud etc. are discharged by the pipeline be connected with sewage draining exit 25.Be provided with an oil-out 26 in the bottom of grease chamber 24, oil-out 26 is connected by the inlet of pipeline with waste oil filter 3, and the liquid outlet of waste oil filter 3 is connected with waste oil recovery pump 4 by pipeline.
In above-described embodiment, the waste oil collecting tank 2 near sand washing hydroecium 23 side can offering a manhole 27, cleaning for manually entering in waste oil collecting tank 2.The waste oil pour spout (not shown) that one directly can topple over waste oil is offered at the top of the waste oil collecting tank 2 near side, grease chamber 24.Also can offer a sample tap and exhaust outlet 28 at the top of waste oil collecting tank 2, the oil vapour that the volatilization of waste oil collecting tank 2 Crude Oil produces carries out cold emptying by the Pipeline transport be connected with exhaust outlet 28 to safe place.
In above-described embodiment, in sand washing hydroecium 23 and grease chamber 24, be provided with liquid level gauge, siren; Weir plate 22 can carry out height and regulate.
In above-described embodiment, be outside equipped with insulation companion thermosphere (not shown) at the tank body of waste oil collecting tank 2, companion's hot temperature degree can based on crude condensation point be arranged, and is generally higher than condensation point 5 DEG C.
In above-described embodiment, waste oil recovery pump 4 adopts can carry out the pump operated centrifugal pump that built the pressure, and flows backward in waste oil collecting tank 2 to prevent the gas-liquid of closed tank platoon.
